Behavior of Mountain Goats in Relation to U.S. Highway 2, Glacier National Park, Montana
Singer FJ. 1978. Behavior of Mountain Goats in Relation to U.S. Highway 2, Glacier National Park, Montana. The Journal of Wildlife Management. 42(3):591-597
A study was conducted in 1975 on mountain goats (Oreamnos americanus) crossing a highway to visit a natural mineral lick. Eighty-seven successful crossings of the highway involving 692 mountain goats were observed, and an estimated 812 crossings occurred during the 1975 lick season. Crossing success was associated (P < 0.05) with the size of groups, all groups (2-55 goats) being more successful than individuals. Crossing success was also associated (P < 0.05) with sex and age of the group leader, the most successful groups being led by an adult nanny with kid at side. Successful highway crossings after July 1 were significantly crepuscular (P < 0.005). Collision hazards and high disturbance during crossings suggested that a goat crossing should be constructed and visitors should be restricted from the crossing area.
